########## File path: drivers/serial/serial.c ########## @@ -1761,7 +1771,7 @@ void uart_connected(FAR uart_dev_t *dev, bool connected) void uart_reset_sem(FAR uart_dev_t *dev) { nxsem_reset(&dev->xmitsem, 0); - nxsem_reset(&dev->recvsem, 0); + nxsem_reset(&dev->recvsem, 1); Review comment: It is more about nxsem_reset function. It knows that sem->semcount is negative, but posts semaphore only if argument is positive. I think something is missing there. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
